Upgrade Servo Arms
Hitec Aluminum Servo Arm (55738) (+$7.95)
Hitec's awesome D89MW is a coreless motor upgrade to the popular D85MG cored-motor servo.  A coreless motor offers faster acceleration, higher speed and higher available power.  The D89MW also offers high input voltage versus the standard-voltage D85MG.  We love the performance, reliability and form-factor of the D85MG... the D89MW improves on it!  This servo has a standardized 25T, 6mm-diameter output spline (D85MG is a classic Hitec 24T).

The D89MW is a micro-size servo, meaning it's case depth measurement is ~12mm and it's weight is ~9-20g.  Being a high-performance micro, it's dimensions are at the upper bounds of the "micro" range.  Applications for this servo are broad in our world of flying wings, but an example would be our own Team Legit 5D2 aircraft.  Performance-wise, the D89MW is the muscle of a "mini" in the body of a "micro!"

Optional Aluminum Arm
D89MW comes with a set of nylon servo arms.  Hitec makes a high-quality aluminum arm sold separately, which mates to the D89MW's 25T-6 output shaft.  Aluminum arms benefit from not only increased durability, but also increased rigidity which improves control feel.  This increased rigidity is especially relevant to the lay-flat servo configurations of the flying wing aircraft we love!

If you would like an aluminum arm included with your D89MW, simply select the corresponding checkbox above.  The HRC55738 arm is available separately here.

Product Description
Engineered with our state-of-the-art D-Series technology, this “micro but mighty” servo is an upgrade from the  popular HS-5085MG. With soft-start enabled circuitry, 4096 high-resolution and a long-life potentiometer, the D85MG allows for smooth and decisive movement and accuracy. Programmable application-specific parameters provide the ultimate in maximum servo performance.  Ideal for 3m gliders; < 40 oz. 3D airplanes; < 70 oz. scale planes and 1/16 or smaller surface vehicles (no internal combustion engines, electric only)
